   I did -- "Alcohol Can Be A Gas", by David Blume.
http://www.permaculture.com
   It's a big book, with pretty complete info on every aspect of alcohol
fuels, from choosing and growing the feedstock, fermenting and
distilling -- both big and small operations, and all an intrinsic part
of a permaculture operation. Also complete info on using alcohol for
fuel, converting engines, etc.
